Most probably you're looking for a demo by Zero Defects or Italian Bad Boys. I can't remember any demo of mentioned groups that features music by Snap though.

Hello StingRay.... I have watched all the ZeroDefects demo I see on my last Tosec but I cannot see the one I was looking for.
I remember that this demo has a sort of slideshow with scene members and a very good music tune from SNAP.

I am looking this demo because there is my picture inside back in the days when I was 22 . Another demos where is my picture is here:http://www.downloadtaxi.com/d/1205410760/
and is from another demo group NIGHTFALL!
